Just want to clear a concept that the formula to compute the no of factors of a number includes identical factors?

2^ 1 ∗3^ 2 ∗5^ 1 =90

therefore, for perfect square, we need to eliminate the identical factors?

Thanks in advance.

The number of factors that you get is only the distinct factors and does not count the identical factors in case of perfect square twice..eg 36=2^2*3^2..no of factors= 3*3=9..they are 1,2,3,4,6,9,12,18,36..hope it clears the doubt
